OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 779,357, dated January3, 1905.

Application filed May 25, 1899. Serial No. 718,296.

To all whom it may concern:

Be it known that I, LEVI S. GARDNER, a citizen oi' the United States,residing at New Orleans, parish of Orleans, State of Louisiana, haveinvented a certain new and useful Improvement in Oil-Cups; and I declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has for its object the production of an oil or lubricatingcup in which there is provided a separate pressure-passage and aseparate oil-passage with means torsimultaneously cutting both off, andalso means for regulating the flow of oil which will not be affected bythe temporary cut-off.

The invention consists in a combination of devices and applianceshereinafter described and claimed.

In the drawings, Figure 1 is a vertical section of my oil-cup. Fig. 2 isa cross-section on the line 2 2 of Fig. 1.

In carrying out the invention, A represents a. suitable casting boredtransversely to receive the plug or cook B, the latter, as well as itsseat, being tapered, as shown, and the plug B held in place andregulated by the nut I). Tapped onto the fitting A and supported therebyis the plate 0, having the vertical tube 0 open at the lower end. andengaged to the fitting A at this point. Extending vertically through thefitting A and plug B are two passages D E.

F is a tube set into the fitting A and communicating with the passage E.

Mounted on the plate C is the glass cylinder G, held in place by theupper plate G, tapped onto the exterior of the upper end of the tube 0.

H is a plug tapped into the interior of the upper end of the tube oandhaving the hand- Wheel 70, whereby it may be screwed into and out ofplace. The tube 0 is slotted vertically on opposite sides, as at 0', topermit the level of the oil to equalize in the cylinder G and tube 0.

Set into the fitting A on its lower side and communicating with thepassage D is a short tube (Z. l

Tapped onto the fitting A at 1' is a hollow fitting J, having slots 1'therethrough and provided with a glass cylinder J. The fitting J isengaged to the casing of the part it is desired to lubricate.

Extending longitudinally into the plug B is a regulating-screw K, thepoint 7 of which is adapted to close the passage D or to regulate theflow through the latter. If desired, a packing cap or nut K may beprovided.

The operation of the device is as follows: By removing the plug H thecup may be filled. By turning the plug B through the handle B until thepassages D E register with the corresponding passages through thefitting A the oil will drop down through the passage D and tube (Z,while the pressure will be equalized through the passage E and tube F.By means of the screw K the flow of oil is regulated. When it is desiredto fill the cup with oil, the handle B is thrown, thus revolving theplug B and cutting off both passages D E. The oil-flow and pressure arethus both shut off without disturbing the oilregulating screw and thecup can be filled without the sight-feed chamber (the cylinder J)filling with oil. In other words, when it is desired to fill the cup theoperator has only to turn the plug B, thus shutting ofl' all thepassages and maintaining the parts in the same position until the plugis turned again, when the oil resumes its flow without disturbing therelative arrangement of the parts.

It is obvious that the regulating-screw K might be located at some otherpoint and IOC or cover having screw-threaded engagement with the upperend thereof, a cylindric shell clamped between said cup and base andforming the side walls of the oil-reservoir, a screwthreaded closure forthe upper end of the slotted tube, a fitting having two passagestherethrough, having screw-threaded engagement with the lower end ofsaid slotted tube, a cut-off valve controlling both passages and aregulating-valve seated in the cut-off-valve closure and controlling oneof said passages, substantially as described.

2. In a lubricating-cup, the combination with an oil-reservoircomprising a base, an integral slotted tube opening axially therethroughand provided with screw-threads in its lower end and on its upper end, acap or cover having screw-threaded engagement with the upper end of saidtube, a shell between said cap and base forming the side Walls of theoil-reservoir, a removable closure for the upper end of the slottedtube, a fitting having screw-threaded engagement with said base in thelower end of the slotted tube and having two passages opening into saidslotted tube, a cut-off valve controlling both passages, aregulating-valve controlling one of said passages, a sight-feed chamberbelow said fitting into which said passages open at their lower ends anda tube extending longitudinally of the oil-reservoir within said slottedtube communicating with one of said passages.

In testimony whereof I sign this specification in the presence of twowitnesses.
